ELEN [110]

Answer:

Step-by-step explanation:

Two events A and B are independent when

$P(A|B)=P(A),$

where $P(A|B)$ is the probability that event A occurs given that event B has occured.

A = randomly selected person is from California

B = randomly selected person preferred brand A

A|B = being a person from California and preferring brand A.

Hence,

$P(A)=\dfrac{150}{275}=\dfrac{6}{11}\approx 0.55\\ \\P(B)=\dfrac{176}{275}=\dfrac{16}{25}=0.64\\ \\P(A|B)=\dfrac{96}{176}=\dfrac{6}{11}\approx 0.55$

Since $P(A)=P(A|B),$ events are independent.

Stella [2.4K]

Answer:

The number of houses built in Town B is 56.

Step-by-step explanation:

We are given that in 2010, the number of houses built in Town A was 25 percent greater than the number of houses built in Town B.

Also, 70 houses were built in Town A during 210.

Let the number of houses built in Town B be 'x'.

So, according to the question;

Number of houses built in Town A = Number of houses built in Town B + 25% of the houses built in Town B

$70 = x + (25\% \times x)$

$70 = x(1+0.25)$

$x=\frac{70}{1.25}$

x = 56

Hence, the number of houses built in Town B is 56.

I need to find sec(theta)= 2(sqrt3)/3

Sloan [31]

Answer: 30° and 330°

<u>Step-by-step explanation:</u>

sec θ = $\frac{2\sqrt{3}}{3}$

sec θ = $\frac{1}{cos(\theta)}$

$\frac{1}{cos(\theta)}$ = $\frac{2\sqrt{3}}{3}$

cos θ = $\frac{3}{2\sqrt{3}}$

cos θ = $\frac{3}{2\sqrt{3}}(\frac{\sqrt{3}}{\sqrt{3}})$

cos θ = $\frac{3\sqrt{3}}{3*2}$

cos θ = $\frac{\sqrt{3}}{2}$

Look at the Unit Circle to see that cos = $\frac{\sqrt{3}}{2}$ at 30° and 330° ( which is equivalent to π/6 and 11π/6)
